Quality of sleep may be linked with childhood obesity

A study in the United States has found that poorer sleep quality was associated with higher body mass index (BMI) in children.

Researchers found that a shorter sleep duration was associated with a higher BMI, similar findings have been found in a number of studies. Each additional hour of sleep was associated with a 1.29cm decrease in waist circumference. Researchers also noted that more fragmented, poorer quality sleep was associated with a higher BMI.
